PRODUCT DETAILS
RallySport Direct carries a large selection of Koyo Radiators from OEM style to racing style radiators to restore or improve the cooling efficiency of your vehicle.
Here, you are looking at the Koyo OEM Replacement Radiator. This radiator has been built to OEM spec to replace your old or leaking factory radiator in your vehicle. This is a direct drop-in replacement with the same build quality and dimensions as your OEM radiator without heavy dealer costs.
DETAILS:
- Designed to meet or exceed the high demands of OEM build quality
- Direct fitment direct replacement
- Features plastic end tanks with an aluminum core allowing for a cost-effective option compared to the OEM units
NOTE:
- This radiator is meant for cars with the automatic transmission with the filler neck NOT on the radiator
- Early model WRX owners need to verify that their stock radiator has a radiator cap as WRX models without a radiator cap need the 2002 WRX radiator
WHY WE CARRY THIS
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
